[michaeltsan]

is there any way to change the input data and the categories? any help?

[javedsha]

Yeah you can. Can you give more details and what exactly you want to achieve. You can load any dataset which are text files and pass the files to CountVectorizer or TfidfVectorizer.

[michaeltsan]

I want to give a text file with sentences, every sentence has one mode of persuasion(there are 3 modes of persuasion in total) and a label which shows which modes it is, to train the model... and then detect modes of persuasion in some other data..

[javedsha]

In your case, each sentence can be a data point with its target.

[michaeltsan]

my problem is that i don't know how to adjust your code on my data

[michaeltsan]

it would be a pleasure if you can give me any help
